# Socket statistics
Plugin: proc.plugin
Module: /proc/net/sockstat
## Overview
This integration provides socket statistics.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
### Default Behavior
#### Auto-Detection
This integration doesn't support auto-detection.
#### Limits
The default configuration for this integration does not impose any limits on data collection.
#### Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
## Metrics
Metrics grouped by *scope*.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
### Per Socket statistics instance
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| ip.sockstat_sockets | used | sockets |
| ipv4.sockstat_tcp_sockets | alloc, orphan, inuse, timewait | sockets |
| ipv4.sockstat_tcp_mem | mem | KiB |
| ipv4.sockstat_udp_sockets | inuse | sockets |
| ipv4.sockstat_udp_mem | mem | sockets |
| ipv4.sockstat_udplite_sockets | inuse | sockets |
| ipv4.sockstat_raw_sockets | inuse | sockets |
| ipv4.sockstat_frag_sockets | inuse | fragments |
| ipv4.sockstat_frag_mem | mem | KiB |
## Alerts
The following alerts are available:
| Alert name | On metric | Description |
|:------------|:----------|:------------|
| [ tcp_orphans ](https://github.com/netdata/netdata/blob/master/health/health.d/tcp_orphans.conf) | ipv4.sockstat_tcp_sockets | orphan IPv4 TCP sockets utilization |
| [ tcp_memory ](https://github.com/netdata/netdata/blob/master/health/health.d/tcp_mem.conf) | ipv4.sockstat_tcp_mem | TCP memory utilization |
